Java 无法从intellij插件部署docker映像

我正在使用intellij 2016.1和docker插件2.1.4。 我正在尝试将一个简单的java容器部署到远程计算机，并得到错误：

未能部署“gaia itest映像Id: gaiaadm/gaia集成测试”：javax.websocket.DeploymentException: 启动WebSocket连接的HTTP请求失败

这是部署日志的输出：

Deploying 'gaia-itest  Image Id: gaiaadm/gaia-integration-tests'...
Creating container...
Container Id: 71afc5f10a0779639543bb7c74235f507d59e24890e66d01fe17a7f90cccc301
Starting container 'gaia-itest'
Attaching to container 'gaia-itest'...
Failed to deploy 'gaia-itest  Image Id: gaiaadm/gaia-integration-tests': javax.websocket.DeploymentException: The HTTP request to initiate the WebSocket connection failed

这是我的Dockerfile：

FROM maven:3.3.3-jdk-8

# Bundle app source
COPY . /src

# Set the working directory
WORKDIR /src

LABEL test=
LABEL test.run.interval=300000

CMD ["mvn","clean","install"]

和容器设置：

{
  "_comment": "gaia-itest",
  "Image": "gaiaadm/gaia-integration-tests",
  "ExposedPorts": {
    "22/tcp": {}
  },
  "AttachStdin": true,
  "OpenStdin": true,
  "HostConfig": {
    "Links":["sts:sts", "whs:whs"],
    "PortBindings":{
      "22/tcp": [{ "HostIp": "0.0.0.0", "HostPort": "2221" }]},
    "RestartPolicy": { "Name": "on-failure", "MaximumRetryCount": 5 }
  }
}

我已连接到docker机器，我可以从浏览器远程访问docker API，并且docker端口已打开。。。 我甚至可以看到intellij运行的容器列表，我看到了我的容器，只是部署失败了

你知道会有什么问题吗
